4DescriptionGitHub Advisory
iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.2, iccDEV is vulnerable to heap buffer overflow in the ToneMap parser. This issue has been patched in version 2.3.1.2.
AnalysisAI
Heap buffer overflow in iccDEV's ToneMap parser (versions prior to 2.3.1.2) allows local attackers with user interaction to achieve information disclosure and denial of service, with potential for code execution. Public exploit code exists for this vulnerability. Update to version 2.3.1.2 or later to remediate.
Technical ContextAI
Classified as CWE-122 (Heap-based Buffer Overflow). Affects Iccdev. iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.2, iccDEV is vulnerable to heap buffer overflow in the ToneMap parser. This issue has been patched in version 2.3.1.2.
RemediationAI
A vendor patch is available — apply it immediately. Fixed in version 2.3.1.2.. Enable ASLR, DEP/NX, and stack canaries where possible.
